  2. Passive optical fiber image transmission technology is a new image transmission technology which used optical fiber image transmission bundle as the relay image transmission device, its important advantages are that it can bend the light course, and can achieve to parallel and real - time planar image soft transmission in the case of passive observation, also it can greatly simplify the structure of long light course system, and reduce the volume of optical instrument, as well as the weight of equipment, so it has wide military and civil application future

    無源光纖傳像技術是一種應用光纖傳像束作為中繼傳像器件的新型的圖像傳輸技術，其重要優點是可實現光路彎曲及被動觀察條件下并行、實時的二維圖像傳輸，並可大大簡化長光路系統結構，減小儀器體積和重量，在軍事上和民用中均具有重要廣泛的應用前景。
  3. Apon is a passive optical network where atm is adopted to transmit broadband and narrowband cells via the sdh frame structure. the service node interface is stm - n. the statistical multiplexing feature of atm enables a concentrated transmission of broadband services in apon

    Apon是在無源光網路中採用atm傳送技術，利用sdh幀結構傳送各種寬帶和窄帶業務的信元，業務節點介面採用stm - n介面。
  4. In pon, the transmission of downlink signal from olt to onu is not complex. usually, the information destined for onus are combined into a multiframe at olt via tdm before reaching the feeder fiber, and then broadcast to each onu via the passive optical demultiplexor. upon receiving the downlink multiframe signal, each onu takes out the part of information for itself only

    在無源光網路中， olt到onu的下行信號的傳輸過程較為簡單，一般在olt將需要發送到各onu的信息採用時分復用的方式組成復幀送到饋線光纖，通過無源光分路器以廣播的方式發送到每一個onu ， onu收到下行復幀信號後分別取出屬于自己的那一部分信息。
  5. Of which, the passive optical network based on atm ( asynchronous transmission mode ) is one of the technologies that can supply the needed bandwidth. it combines the multi - services and multi - bit rate ability of atm and the transparent transfer ability of pon, has higher technique dominance, and attracts many attentions

    其中，以atm為基礎的無源光網路（ atm - pon或apon ）是能夠提供所需帶寬的技術之一，它結合了atm多業務和多比特率的支持能力和pon的透明寬帶傳輸能力，具有較高的技術優勢，因而備受各國的關注。
  6. Many advantages make optical fiber suitable used as transmission medium of high - rate broadband services, such as broad transmission band, large capacity, low loss, strong immunity to interference etc. among optical access network, passive optical network ( pon ) is paid more attention throughout the world. it offers easily upgraded and low cost of lay, ope ration and maintenance. especially passive optical network based on atm ( atm - pon ) integrates the capability of supporting multiple qos services with atm and transparent transmission with pon

    在光纖接入網中，無源光網路（ pon ）由於不採用有源節點、敷設和運行維護成本低且成本共享、對業務透明、易於升級等優點而備受世界各國的關注，特別是以atm為基礎的無源光網路（ atm - pon ） ，由於結合了atm多業務、多比特率的支持能力和pon的透明寬帶傳送能力，將成為實現未來寬帶接入乃至最終實現ftth的重要方式。
